Letters Patent No. 100,589, dated March 8, 1870.

The Schedule referred to in the'se Letters Patent and making part of the lar-une.-

To alllt'hom tt may concern:

Be it known thatI, ISAAC BONNELL, Jr., of Chicago, iu the county of Cook, and State of Illinois, have invented a Dust and Cinder-Exeluder for OarWVindows;

and I do hereby declare that the following is a full,

clear, and exact description thereof,V which willenable those skilled in the art to vmake and use the same, refviding `ctn-windows with projecting frames o'r flanges, which, while they do' notY exclude the view freni the inside of the car, prevent dust, cinders, Sec., from entering the windows when-open for the purpose of veutilation, and prevent the glass frein being obscured by such dust, cinders, Ste., when the -windows are closed.

A. represents an ordinary railroad car, in which is `placed several styles of car-windo\i*S-no`w most in com Mylinvention consists in placing around these windows, [langes or frames B EF, which project outward from the car from two to four` inches, in orderthat when the car is i'nV motion, dust, cinders,-sparks, 85e., may be carried by the windows or caught by the frames, and -thus prevented from entering thecar.

In making the device,',thin strips of wood vmay be mitered together at the angles, and-.secured bynails or screws to the u-tsideof'the jambcasing, -as shown at figs. 1 and :.l., or flanges may be formed on the strips for the conveniencel of fastening them to the at side ot the car, closely to the jamb-casings, as shown at F, same iigures.

XVroughtor eastiron frames may be used, similarly constructed to `those shown` at W V. In this case, iianges G may beformed on them to fastento the flat sides of aA car, or they may be formed to fasten to the ja1nb-casings like the frames shown at windows S S. The iron frames or anges, however, can, when the Windowsv have arched tops, be provided at less cost than wooden ones,rand they may have any ornamental style which' is desired.

In the drawings, the car-windows are placed far `enough to use a separate frame for each window; but some cars have windows placed so closely together that a partiti0niraine between them, connected by top and bottoni flanges, will fully answer the purpose.

The top and bottom parts of the frames are equally as necessary as the side pieces, for when a train of cars isvmoving, the direction of the current of air is frequently upward and downward, carrying what moving dust, Sac., there may be with it. This especially is the case when the cars are moving overa broken country, passing through cuts, and bybuildings, Ste.

It will be seen -from this description, that the device not only prevents dustfroui entering the car when the sashes are raised up, but that it prevents dust, cinders, smoke, &c., from coming in contact with the glass when the sashes are shut, and obscuring a view from the inside of the car. In this respect the device differs from the ordinary projecting ventilator-,inasmuch as such ventilator has no glass window to protect.

Having thus described my invention,

What l claim, and desire to secure by Letters Patent, is-

Providing car-windows, having sliding sashcs'there in, with projecting box frames, which surround said windows and serve t0 keep dust, cinders,&c., out of the car when it is in motion, and the sashes are raised up, and to keep such dust, cinders, Snc., from coming in contact with the -glass when the sashes are shut, as specified.
